NXP introduces a new generation of automotive position sensors

     NXP Semiconductors N.V. introduced a new generation of automotive position sensor KMA210. The KMA210 integrates NXP's latest magnetoresistive sensor chips and a unique signal conditioning ASIC circuit based on NXP's advanced insulated silicon (SOI) ABCD9 process. The KMA210 is the first member of a new family of magnetic sensors and is a complete system-level package solution that requires no external components. The KMA210 is specifically designed to improve the overall performance and robustness of automotive applications.

     From electronic steering and active suspension systems to automotive headlight regulation, the KMA210 is suitable for all automotive applications that require precise measurement of mechanical angles. Because of its high accuracy and robustness, it is particularly suitable for powertrain applications under the hood, throttle control and air control valve measurement. In addition, the sensor is extremely stable over high temperatures (up to 160°C), making it ideal for exhaust gas recirculation (EGR) applications where it is the core of exhaust gas emission control.

     NXP magnetoresistive position sensors improve safety, environmental protection and comfort during the ride. The KMA210 sensor helps regulate untreated engine exhaust emissions, thereby supporting the global mission of reducing CO2 emissions from vehicles. For example, in diesel engines, the regeneration of diesel particulate filters can be facilitated by throttling the intake air needed to reduce particulate emissions. In in-line engines, with NXP's magnetoresistive position sensors, ETC actuators can act as load control and idling speed control devices, enabling precise control of the intake air and facilitating cruise control or electronic stability program (ESP) functions.

     The sensor-integrated signal conditioning ASIC circuit is made using NXP's proprietary 140nm CMOS automotive-grade insulated silicon process ABCD9, providing a significant increase in electromagnetic compatibility (EMC) compared to previous sensor products with integrated ASics. The device integrates two embedded capacitors in the same package, eliminating the need for a printed circuit board and external filters, thereby reducing system costs. The KMA210 sensor conforms to the new HMM (Human Body Metal Model) specification and not only has excellent robustness, but also excellent electrostatic discharge (ESD) performance. At the same time, the sensor is completely temperature compensated and can be used out of the box.

     Drue Freeman, vice president of Global Sales and Marketing at NXP Semiconductor Automotive Electronics, said: "NXP builds on its leading product and application expertise to deliver innovative automotive technology platforms that improve environmental, safety and comfort in driving. We worked closely with our key customers from the beginning of the design process, and they provided us with valuable advice to help us establish the conditions necessary to meet the automotive industry's high requirements for EMC and ESD performance. "The result is an industry-leading and robust device based on NXP's latest ABCD9 process and our extensive experience in high-performance mixed signal."
